MACHINE FOR TURNING CAR-AXLE JOURNALS.

To all whom it may concern:

Be it known that I, JULIUS J. AOKER, a citizen of the United States, and a resident of the city of Horton, in the county of Brown and State of Kansas, have invented a new and useful Improvement in Machines for Turning Car-Axle Journals, of which the following is a specification.

This invention relates to machines for turning car axle journals and hub bearing faces, and more particularly on damaged axles.

It has for its principal objects to produce a machine for turning and truing the ournals and hub bearing faces without removing the wheels from the axles, to provide for readily changing the machine for use in connection with axles having either outside or inside journals, and to attain certain advantages hereinafter more fully appearing.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings which form part of this specification and wherein like symbols refer to like parts wherever they occur,Figure 1 is a front elevation of a machine showing, in full lines, an arrangement according to my invention for turning outside journals, and in dotted lines, an arrangement for inside ournals; Fig. 2 is an end elevation; Fig. 3 is a top plan view; and Fig. 4 is a horizontal section taken on or about the line 4-4 of Fig. 1.

The frame of the machine may obviously be constructed of cast metal sections and bolted or otherwise secured together or, as shown, of commercially rolled angle iron and channel sections and plates. The base, as shown, comprises longitudinal members 1 which are bolted or riveted to transverse members 2. Preferably, the longitudinal members comprise plates 1 piled fiatwise and riveted together, and stiifened by angles 1 The transverse members are preferably angles. It is also preferable to have the longitudinal members at the middle and one side only of the base.

At the opposite ends of the base are posts 3. The posts are each preferably composed of two channels 3 placed back to back and riveted to an interposed filler plate 3*. The posts are braced by inclined angle iron stays or braces 4.

Specification of Letters Patent.

Application filed January 20, 1911.

Patented Oct. 31, 1911.

Serial No. 603,620.

Secured to the top portions of the posts 8 is a horizontal beam or longitudinal connecting member 5 comprising two angles riveted together to form a substantially T-shaped section. The middle portion of the beam 5 is slotted longitudinally as at 6 and the portions of the two angles comprising the beam which are cut away to provide this slot are reinforced by angles 7.

Secured on the top of the beam 4, at the left hand portion thereof, is a plate 8. Mounted on this plate is an air-hoist cylinder 9 whose piston is connected to a wire cable or a chain 10 which passes over a pulley 11 j ournaled on the plate 8. The cable or chain 10 hangs through a slot or perforation 12 in the plate and through said slot 6 in the beam 5; and it has secured on its end a hook or grapple 13 for the purpose of lifting the axle into position to be engaged by the pivots or centering studs 14 on. which the axle is turned. The centering studs 14 project horizontally inward from the end posts 3 and the same are obviously adjustable, and one or both of them, as desirable, may have a hand-wheel 15 thereon for convenience in manipulating them.

Mounted on the base are two tool holders 16, the one on the left being located in position for turning outside journals and hub faces, and the other for those of the inside type. By full lines in Fig. 1, an axle having outside ournals is shown in position to be operated upon, and by dotted lines, an axle of the inside journal type is shown. In cases where the machine is to be used for the latter type of axle a supplemental post 3 is placed in the machine as shown by the dotted lines, because the distance between centers is shorter. This post is made removable and temporarily secured in place. Also, when the machine is so arranged, the plate 8 carrying the air-hoist cylinder 9 is shifted toward the right so as to bring the hook or grapple 13 over the middle of the axle.

Located above the'machine is a countershaft 17 on which a pulley or drum 18 is fixed. The countershaft may be driven by a belt running over a pulley 19 fixed thereon or by any other desirable means. A belt 20 is passed over the drum 18 and right hand car wheel, whereby the axle is rotated.

Pivotally and slidably mounted on a horizontal rod 21 supported by uprights 22 on the beam 5 is a yoke 23. This yoke has a grooved or flanged idler 2% j ournaled thereon and adapted to bear against the belt 20; and slidahly mounted on the outer exten sion 25 of the yoke is a weight 26. By this arrangei'nent, the slack in the belt is taken up.

Fixed on the end of the countershaft 17 is a crank 27 which is connected by a link or rod 28 to one of the arms 29 fixed on a rock-shaft 30 journaled in brackets 31 extending laterally from the beam 5. The two rock-arms 29 are respectively connected by chains 32 to the actuating levers or arms 33 for the operating mechanisms of the two tool holders 3% on the carriages 16. The op erating mechanisms of the tool holders are of the usual and obvious ratchet and feedscrew type. Hence, as the rock-arms 29 are oscillated through the medium of the connection of the link 28 with the crank 27 the motion is transmitted through the chains 32 to the levers 33 of the respective tool feeding mechanisms. There is a positive upward pull on the levers by the chains while the downward movement of the levers is effected by gravity; and the cutting tool is thereby intermittently moved.

In the operation of the machine, it is first arranged for outside or inside journals, as the case may be, as above set forth. The axle with the wheels thereon is then lifted into position and centered on the centering studs 14L. The cutting tool is adjusted with respect to the journal to be turned or trued, and the driving belt is slipped onto the tread portion of the car wheel. After the operation on the journal is completed, the axle is reversed end for end in the machine and the opposite journal is operated upon in the same manner. It is, of course, obvious that the chain connection may be broken between the rock-arm 29 and the particular toolactuating mechanism not in use.

Obviously, the machine admits of considerable modification without departing fro n my invention. Therefore, I do not wish 0 be limited to the specific construction and arrangement shown.
